SIGMUND FRIEDMAN, OF PATERSON, NEW JERSEY.

RAIL-TIE.

roac es.

To all whom it may concern:

Be it known that I, SIGMUND FRIEDMAN, a citizen ot the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented new and useful Impro vemcnts in Rail-Ties, of which the :t'ollowing is a specification.

The present invention relates to improve ments in railway ties.

The primary object of the invention is to produce a reinforced plastic tie provided with rail-receiving cushions, which are so arranged upon the tie as to impart the desired amount of elasticity to absorb all the shocks and ars incident to the rolling stock passing over the rails upon the ties, and so co-nnoletely overcome the liability of breakage to the tie and the injury to the rolling stock incident to the non-yielding of the ordinary plastic tic.

A further object of the invention is the provision with a plastic tie of wooden railreceiving cushion blocks which are so arranged upon the tie as to prevent the accidental displacement thereof, but which, may, when desired, be easily and quickly removed without interfering with the tie or with the rail upon the tie.

1 still further object of the invention is the provision of a reinforced plastic tie which formed adjacent its ends with re cessed portions, the opposite walls of which being inclined, and the lower wall ot' which being :t'ormed with a depression, the said depression adapted to receive a rail supporting cushion member which has beveled ends that co-act with the inclined side walls of the recess and having its lower ends resting upon the flat :t'ace provided by the recess, while its central portion is disposed over the depression of the tie, and the rail is supported upon the face of the tie directly opposite the depression so that the central portion of the cushion is permitted a desired amount of yieldability within the depression and the weight of the load upon the rail directed to the opposite beveled ends and to the lower faces of the said cushion which rest upon the walls provided by the recess.

A still further object of the invention is the construction of a reinforced plastic tie which is so shaped as to obviate all likelihood of the tie moving or working out of place when it is once embedded in the earth.

With the above recited objects in view,

and others which will appear as the nature of the invention is more fully imderstood, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and talling within the scope of the appended claims.

In the drawing: Figure l is a perspective view of one end of a tie constructed in accordance with the present invention and illustrating the cushion block in position thereon, Fig. 2 is a side elevation showing the rail chair arranged upon the tie and engaging a rail, the ail being shown in section and parts ot the tie being broken away, Fig. 3 is a vertical longitudinal sectional view on the line of Fig. 2, and Fig. it is a top plan view of the parts illustrated in Figs. 2 and 3, the rail being removed. Fig. 5 is a detail perspective view of one of the cushions.

Referring now to the drawing in detail, the numeral 1. designates my improved tic which molded from concrete or other suit:- able plastic material, and which is provided with suitable metallic rcin'torcemcnts 2. The ends of the ties have their reintorcements, preferably in the term of metallic bars, while the central portion ot' the tie is rein forced by a metallic basket, as clearly shown in Fig. 3 of the drawing. The body of the tie is of a trapezoidal shape in cross section, the narrower :tarc serving as the bottom. The undertace ot the tie is made concavcd, as shown at 23, the concavity being formed at suitable distances 't'ron'i the ends of the tie and serving, when the tie is embedded in the ground, to prevent the body thereoit 'trom moving or working endwisc. At the same time, the tapering sides ot the tie gives greater bearing surface for tamping and tacilitates the removal oi. the tie from the ltttttllJGtl. The ends oi the tie have their upper tacos recessed transversely, as indicated by the numeral 5', the lower wall formed by the said recess, and designated by the niuneral (3, is liat; and horizontally straight. The end walls formed by the recess are undercut or beveled to provide, what I will term, ribs 7, and the upper faces of the said ribs are disposed a suitable distance below the top face of the tie, as are the side faces of the said ribs arranged a suitable distance from the opposite side faces of the said tie. The lower wall (3 of the recess 5 is centrally formed with a depression 8, the width of the depression equaling or slightly exceeding the width of the base flanges of the rail R.

The numeral 9 designates a cushioning block or wood filling which has its opposlte ends inclined or beveled and which contact-- ing with the beveled faces of the ribs 7 pro vide a dove-tailed fit for the said member 9. The lower face of the member 9 rests upon the wall 6 of the recess 5, so that its central portion is disposed over the depression 8, and, as previously stated, the rail R resting upon the central portion of the upper face of the cushioning member 9, or upon the base plate of a rail chair which may be positioned upon the said upper face of the memher 9, is arranged directly over the recess 8, so that the load of the rolling stock upon the rail R will permit of the central portion of the block bending slightly within the clepression 8, but, at the same time, directing most of the weight to the ends of the block and to the portions thereof resting upon the wall 6, thus the said block 9 permits of the desired amount of resiliency and overcomes the defects of a rigid tie, or of a plastic tie having cushioning members not arranged to receive the load and strain in a manner as just described.

Any desired means may be employed for sustaining the cushion member 9 upon the tie without permitting of the outward creeping or movement of the said block, but, I prefer to have the said block of a width corresponding with the width of the ribs 7 and to fill the space thus provided by side flanges 10 formed on one of the longitudinal edges of the base 11 of a rail chair 12. The chair comprises a pair of members having interengaging base members which are arranged upon the upper face of the block 9, so that the said chair will not interfere with the resiliency of the block, while suitable means are provided for connecting the sections so that the flanges will effectively conceal the cushioning member 9 and thus retain the same upon the tie.

From the above description, it will be noted that the flanges of the rail chairs are arranged flush with the sides of the tie, and it is thought that the simplicity and advantages of the construction will be apparent to those skilled in the art to which such inventions appertain without further detailed description.

Having thus described the invention, what I claim is:

l. A railroad tie constructed of reinforced plastic material, the tie having its upper face adjacent its ends recessed transversely, the end walls of each of the recesses being beveled inwardly, the bottom wall having a centrally arranged elongated depression, a cushioning block having its edges beveled to engage the said beveled end walls of the re cess, and a rail adapted to rest upon the cushioning member directly above the clepression, substantially as and for the purpose set forth.

2. A railroad tie having its bottom centrally concaved, its sides inclined from its bottom to its top, its top, adjacent its ends, recessed transversely, each recess having undercut ribs extending along the corners thereof, the lower wall of the recess having a centrally arranged elongated depression, a cushioning blOCK having its edges beveled to engage the undercut ribs to provide a dove-tail fit in said recess, and rail sustain ing means comprising interlocking members having flanges engaging with the sides of the cushioning block to retain the said block within the recess.

3. A railroad tie having transverse recesses in each end, the side walls of the recess having inwardly projecting lips which overlie the lower wall of said recess, the said lower wall of the recess being provided with a centrally arranged elongated depression, a cushioning member arranged within the recess to rest upon its lower wall and to have its opposite face frictionally contact with the lips provided by the side walls of the recess, whereby, a load arranged centrally upon the block will permit the said cushioning member yielding centrally within the depression and have its ends forced against the inwardly projecting lips provided by the recess.

In testimony whereof I affix my signature \VM. Konnrrr, BENNETT S. .TONES.
